TomTom, the company best known for its auto navigation systems, has opened its mapping data for app developers, making it easier for companies to make programs that could rival those from Google and Apple.

TomTom is one of the world's biggest navigation product makers. Like its rivals, it has struggled as more people use their smartphones and tablets to find their way round. It supplies maps and related content to the majority of handset makers, including Apple, RIM, HTC, Samsung, and Google, but the new developer program could boost its customer base even further.

Reuters noted that the new program is free on a trial basis, but it charges a fee if developers use the data for commercial purposes.
